Answer 8

I will give you an example:
\(\large\color{black}{ 7x-2y=11 }\)

\(\large\color{black}{ 7x-2y\color{red}{-7x}=11\color{red}{-7x} }\)

\(\large\color{black}{ -2y=11-7x }\)

\(\large\color{black}{ \color{red}{\frac{\LARGE \color{black}{-2y} }{\LARGE -2}}=\color{red}{\frac{\LARGE \color{blacK}{11} }{\LARGE -2}}-\color{red}{\frac{\LARGE \color{blacK}{7x} }{\LARGE -2}} }\)

\(\large\color{black}{ y=-\color{black}{\frac{\LARGE \color{black}{11} }{\LARGE 2}}+\color{black}{\frac{\LARGE \color{black}{7} }{\LARGE 2}}x }\)

\(\large\color{black}{ y=\color{black}{\frac{\LARGE \color{black}{7} }{\LARGE 2}}x-\color{black}{\frac{\LARGE \color{black}{11} }{\LARGE 2}} }\)
